Abstract

A method of testing an integrated circuit includes connecting a conductive line to a ground voltage. The method further includes directly physically contacting the conductive line with a first conductive structure. The method further includes contacting the conductive line with a second conductive structure different from the first conductive structure. The method further includes supplying a first test voltage to the conductive line through the first conductive structure. The method further includes supplying a second test voltage to the conductive line through the second conductive structure. The method further includes generating a report indicating whether the first conductive structure is capable of carrying the first test voltage based on feedback from a first test circuit connected to the first conductive structure.
